WalkthroughThis update introduces a comprehensive Facebook Pages webhook trigger system. It adds a suite of new event sources for various Facebook Page activities—such as new posts, comments, reactions, shares, messages, and page updates—each implemented as a modular source. Supporting documentation and a common webhook handler are included. The legacy app definition and related ignore file are removed. Changes

🧹 Nitpick comments (4)
components/facebook_pages/sources/new-feed-activity/new-feed-activity.mjs (1)
18-40: Fix message truncation logic to avoid unnecessary ellipsis.The metadata generation is well-implemented, but there's a minor issue with the message truncation logic.
if (data.message) { - summary += `: ${data.message.substring(0, 50)}...`; + const truncatedMessage = data.message.length > 50 + ? `${data.message.substring(0, 50)}...` + : data.message; + summary += `: ${truncatedMessage}`; }This prevents adding "..." when the message is already 50 characters or shorter.
components/facebook_pages/sources/common/webhook.mjs (1)
42-50: Add error handling for subscription deletion.The deactivation should handle and log errors when deleting subscriptions.
async deactivate() { const pageId = this._getPageId(); if (pageId) { - await this.app.deletePageSubscription({ - pageId, - }); + try { + await this.app.deletePageSubscription({ + pageId, + }); + } catch (error) { + console.error("Failed to delete page subscription:", error); + // Don't rethrow - best effort cleanup + } } }components/facebook_pages/sources/new-post/new-post.mjs (1)
13-15: Remove unused getObject method.The
getObjectmethod is not part of the common webhook interface and appears to be unused.methods: { ...common.methods, - getObject() { - return "page"; - }, getFields() { return [ "feed", ]; },components/facebook_pages/sources/new-message/new-message.mjs (1)
18-37: Improve summary truncation logic.The summary generation logic is mostly correct, but the text truncation always adds "..." even when the text is 50 characters or less.
Apply this diff to fix the truncation logic:
let summary = "New message received"; if (message?.text) { - summary = `New message: ${message.text.substring(0, 50)}...`; + const truncatedText = message.text.length > 50 + ? `${message.text.substring(0, 50)}...` + : message.text; + summary = `New message: ${truncatedText}`; } else if (message?.attachments?.length > 0) { summary = `New message with ${message.attachments.length} attachment(s)`; }

components/facebook_pages/facebook_pages.app.mjs (4)
104-108: LGTM! Well-defined property for Facebook App ID.The
appIdprop is properly structured with appropriate type, label, and helpful description referencing where users can find this value.
147-152: LGTM! App access token retrieval method.The method follows the established pattern using
_makeRequestand targets the correct Facebook API endpoint for obtaining app access tokens.
235-252: LGTM! Subscription management methods are well-implemented.Both
createSubscriptionanddeleteSubscriptionmethods correctly use the Facebook API endpoints for managing app-level webhook subscriptions. The methods follow the established patterns and destructure parameters appropriately.
253-272: LGTM! Page subscription methods are correctly implemented.Both
createPageSubscriptionanddeletePageSubscriptionmethods properly use the/subscribed_appsendpoint and include thepageIdparameter for page-specific authentication, which is consistent with other page-level methods in this file.components/facebook_pages/package.json (2)
3-3: Appropriate version bump for new functionality.The version bump from 0.1.0 to 0.2.0 correctly reflects the significant new webhook functionality being added to the Facebook Pages component.
16-16: Double-check Facebook Pages component imports after upgrading to @pipedream/platform v3.1.0
We’ve upgraded from ^1.5.1 to ^3.1.0—a major version bump—so please verify that the following exports and APIs haven’t changed or been deprecated in v3:
- components/facebook_pages/facebook_pages.app.mjs (import { axios } from "@pipedream/platform")
- components/facebook_pages/actions/create-post/create-post.mjs (import { ConfigurationError } from "@pipedream/platform")
Ensure axios and ConfigurationError are still available and behave as expected under v3, and update any calls if the platform API has changed.
components/facebook_pages/sources/README.md (1)
1-80: Excellent comprehensive documentation for Facebook Pages webhook sources.This README provides thorough documentation covering all aspects of the new webhook functionality:
- Clear descriptions of all 7 webhook sources
- Step-by-step setup instructions with Facebook App configuration
- Common properties and event data structure
- Practical troubleshooting guidance
The documentation will help users understand and successfully implement the webhook sources.
components/facebook_pages/sources/new-share/new-share.mjs (3)
13-17: LGTM! Correct field specification for feed monitoring.The
getFields()method correctly returns["feed"]to monitor Facebook Page feed changes, which is appropriate for share events.
18-37: LGTM! Well-implemented metadata generation.The
generateMetamethod properly:
- Converts Facebook's timestamp from seconds to milliseconds
- Generates a unique ID using
share_idor a fallback pattern- Creates informative summary text including the sharer's name when available
The implementation is consistent with other Facebook Pages sources.
38-50: LGTM! Proper event filtering for share events.The
processEventmethod correctly filters webhook changes to only process share events by checking bothitem === "share"andverb === "add". This ensures the source only emits events for new shares and ignores other feed activities.components/facebook_pages/sources/new-feed-activity/new-feed-activity.mjs (2)
13-17: LGTM! Correct field specification for feed monitoring.The
getFields()method correctly returns["feed"]to monitor all Facebook Page feed changes, which is appropriate for a general feed activity source.
41-47: LGTM! Appropriate event processing for general feed activity.The
processEventmethod correctly processes all feed-related events without additional filtering, which is appropriate for a general "feed activity" source that should capture posts, comments, reactions, and shares.components/facebook_pages/sources/common/webhook.mjs (3)
1-24: LGTM! Well-structured webhook properties.The setup with crypto-based token generation and proper prop definitions follows security best practices.
51-67: LGTM! Proper abstract method pattern.The abstract methods with clear error messages correctly enforce implementation in subclasses, following established patterns.
68-91: LGTM! Correct webhook verification implementation.The webhook verification properly follows Facebook's protocol with appropriate status codes and logging.
components/facebook_pages/sources/new-reaction/new-reaction.mjs (3)
1-17: LGTM! Proper source configuration.The source setup correctly extends the common webhook and subscribes to the appropriate field.
18-40: LGTM! Well-structured metadata generation.The method properly handles optional fields with fallbacks and generates descriptive summaries.
41-53: LGTM! Correct event filtering.The method properly filters for new reaction additions on the feed.
components/facebook_pages/sources/new-comment/new-comment.mjs (3)
1-17: LGTM! Proper source configuration.The setup correctly extends the common webhook for comment events.
44-56: LGTM! Correct comment filtering.The method properly identifies new comment additions.
18-43: Add null check for message before substring.The code could throw an error if
messageis undefined when callingsubstring.let summary = "New comment"; if (from?.name) { summary = `New comment by ${from.name}`; } if (message) { const preview = message.substring(0, 50); summary += `: ${preview}${message.length > 50 ? "..." : ""}`; }The current code already has the null check, so it's safe.
components/facebook_pages/sources/page-updated/page-updated.mjs (3)
1-17: LGTM! Appropriate naming for update events.The source correctly uses "Page Updated" without the "New" prefix, following guidelines for update events.
46-58: LGTM! Appropriate filtering for page updates.The method correctly identifies both status updates and page edits.
18-45: Add null check before accessing data.message.Line 31 could throw an error if
data.messageis undefined.let summary = "Page updated"; if (item === "status" && verb === "add") { summary = "Page status updated"; if (data.message) { const preview = data.message.substring(0, 50); summary += `: ${preview}${data.message.length > 50 ?

47-59: LGTM! Correct post filtering.The method properly identifies new post additions on the feed.
components/facebook_pages/sources/new-message/new-message.mjs (6)
1-10: LGTM! Component structure follows Pipedream conventions.The import statement, component extension pattern, and metadata properties are correctly implemented according to Pipedream source component standards.
13-17: LGTM! Correct field specification for message events.The
getFields()method correctly returns["messages"]which is appropriate for Facebook Pages message webhooks, distinct from other webhook sources that typically listen to "feed" events.
38-48: Verify the single message return behavior.The
processEventmethod returns only the first message found in the messaging array. Ensure this aligns with the expected behavior, as Facebook might send multiple messages in a single webhook payload.Consider whether all messages should be processed or if returning the first one is intentional. If multiple messages need to be handled, the method should be refactored to return an array or the calling code should iterate through all messages.
50-75: LGTM! Proper webhook verification implementation.The webhook verification logic correctly implements Facebook's verification protocol by checking the mode, verify token, and responding appropriately with the challenge or 403 status.
77-81: LGTM! Correct immediate response pattern.Responding with HTTP 200 immediately after receiving webhook events is the correct pattern for webhook handlers to prevent timeouts.
1-105: Well-structured component that aligns with PR objectives.This component effectively implements the Facebook Pages message webhook trigger as specified in the PR objectives. The dual processing approach (handling both
entry.messagingandentry.changesformats) demonstrates good understanding of Facebook's webhook variations.The component properly extends the common webhook base and implements the required methods for webhook lifecycle management. The code structure follows Pipedream conventions and provides appropriate event metadata.

🤖 Prompt for AI Agents
In components/facebook_pages/sources/common/webhook.mjs around lines 26 to 41,
the activate method lacks error handling for the asynchronous
createPageSubscription call. To fix this, wrap the subscription creation in a
try-catch block, and only call _setPageId and log success messages if the
subscription succeeds. In the catch block, log or handle the error appropriately
to prevent storing invalid state when subscription creation fails.

🛠️ Refactor suggestion
Add error handling in event processing loop.
The event processing should handle errors gracefully to prevent one malformed event from affecting others.
// Handle webhook events
this.http.respond({
status: 200,
});

body.entry.forEach((entry) => {
if (entry.changes) {
entry.changes.forEach((change) => {

- this.$emit(eventData, meta);
- }

the event processing loop lacks error handling, which means a single malformed
event could disrupt processing of others. Wrap the processing logic inside the
forEach loops with try-catch blocks to catch and log errors without stopping the
iteration, ensuring all events are processed independently and errors are
handled gracefully.

Add error handling and consider webhook signature verification.
The event processing logic handles both messaging and changes formats appropriately, but could benefit from improved error handling and security measures.
Consider adding error handling around the generateMeta and $emit calls:
if (messagingEvent.message) {
- const meta = this.generateMeta(messagingEvent);
- this.$emit(messagingEvent, meta);
+ try {
+ const meta = this.generateMeta(messagingEvent);
+ this.$emit(messagingEvent, meta);
+ } catch (error) {
+ console.error("Error processing message event:", error);
+ }
}Also apply similar error handling to the changes processing block.
Verify whether webhook signature validation should be implemented for security. Facebook typically provides an X-Hub-Signature header that should be validated to ensure the webhook is actually from Facebook.

Add error handling and Facebook webhook signature verification
To align with other sources (Intercom, Superdocu, Twitch) and improve robustness, please:
• Validate the X-Hub-Signature header before processing any body.entry events (e.g. using this.isSignatureValid or a verifyWebhookRequest helper).
• Wrap both the messaging‐event and changes‐event paths in try/catch around generateMeta/$emit to prevent a single failure from breaking the entire webhook handler.
Suggested changes in components/facebook_pages/sources/new-message/new-message.mjs (at the top of your async run(event) or equivalent entrypoint):
async run(event) {
+ // Verify Facebook webhook signature
+ if (
+ this.clientSecret &&
+ !this.isSignatureValid(event.bodyRaw, event.headers["x-hub-signature"])
+ ) {
+ this.logger.warn("Invalid X-Hub-Signature; skipping event.");
+ return;
+ }
const body = event.body;
if (body?.object === "page" && body?.entry) {
for (const entry of body.entry) {
if (entry.messaging) {
for (const messagingEvent of entry.messaging) {
- const meta = this.generateMeta(messagingEvent);
- this.$emit(messagingEvent, meta);
+ try {
+ const meta = this.generateMeta(messagingEvent);
+ this.$emit(messagingEvent, meta);
+ } catch (err) {
+ this.logger.error("Error emitting messaging event:", err);
+ }
}
} else if (entry.changes) {
for (const change of entry.changes) {
- const eventData = this.processEvent(change);
- if (eventData) {
- const meta = this.generateMeta(eventData);
- this.$emit(eventData, meta);
- }
+ const eventData = this.processEvent(change);
+ if (!eventData) continue;
+ try {
+ const meta = this.generateMeta(eventData);
+ this.$emit(eventData, meta);
+ } catch (err) {
+ this.logger.error("Error emitting change event:", err);
+ }
}
}
}
}
}Please implement or reuse a signature‐validation helper (as in
components/intercom/sources/new-topic/new-topic.mjs, components/superdocu/sources/new-event/new-event.mjs, or components/twitch/twitch.app.mjs) and ensure you have access to event.bodyRaw and event.headers.

to 103, add validation for the X-Hub-Signature header before processing
body.entry events by implementing or reusing a signature verification helper
like this.isSignatureValid or verifyWebhookRequest, ensuring access to
event.bodyRaw and event.headers. Additionally, wrap the code blocks that call
generateMeta and this.$emit for both messagingEvent and changes event paths in
try/catch blocks to prevent one failure from stopping the entire webhook
